Bumps the npm_and_yarn group with 1 update in the /apps/sim directory: undici.

Updates undici from 7.25.0 to 7.28.0

Release notes

Sourced from undici's releases.

v7.28.0

⚠️ Security Release

This release line addresses 7 security advisories, all shipped in v7.28.0.

Action required: Upgrade to undici 7.28.0 or later.

npm install undici@^7.28.0

The v7 line is not affected by GHSA-38rv-x7px-6hhq (CVE-2026-9675), which is an 8.x-only regression.

Note on GHSA-hm92-r4w5-c3mj: this fix shipped in v7.28.0, not the earlier 7.2x line — the vulnerable single-pool code was still present through v7.27.2. The per-origin pool fix is 3805b8f8 (#5041).

High severity

WebSocket DoS via fragment count bypass — CVE-2026-12151

GHSA-vxpw-j846-p89q · CWE-400, CWE-770 Fix: 8cb10f98 websocket: limit the number of fragments in a message (part of backport a027a4a0 Backport WebSocket maxPayloadSize fixes to v7.x, #5423)

A malicious WebSocket server can stream a large number of small or empty continuation frames. Undici enforced a limit on cumulative payload size but did not limit the number of fragments per message, leading to unbounded memory growth and denial of service.

  • Affected: applications using new WebSocket(...) or WebSocketStream against untrusted endpoints.
  • Workaround: none — upgrade is required.

PR Summary

Low Risk
Single-version dependency bump with no app code changes; it reduces HTTP/WebSocket-related security exposure in a well-scoped patch release.

Overview
Bumps the undici dependency in apps/sim from 7.25.0 to 7.28.0 (patch/minor within the v7 line).

7.28.0 is a security release that fixes multiple advisories (including WebSocket DoS, SOCKS5 TLS validation, and per-origin pool routing). The app uses undici directly for server-side pinned HTTP fetch in input-validation.server.ts, so this is primarily a dependency hygiene / vulnerability remediation change with no application code edits in this PR.

Greptile Summary

This PR bumps undici from 7.25.0 to 7.28.0 in apps/sim/package.json as a security release addressing 7 CVEs across WebSocket DoS, TLS certificate validation bypass, cross-origin routing, and cache header handling.

  • Resolves 3 High-severity CVEs (CVE-2026-12151, CVE-2026-9697, CVE-2026-6734): WebSocket fragment-count DoS, SOCKS5 TLS bypass, and cross-origin pool routing — all requiring an upgrade with no available workaround.
  • Resolves 2 Moderate and 2 Low severity CVEs related to cache field trimming and SOCKS5 authentication state enforcement.

Confidence Score: 5/5

Safe to merge — a single-line version bump in package.json applying a security release with no functional or API changes to application code.

The change is a dependency upgrade driven by a security release. The new version is a patch/minor-compatible bump (7.25.0 → 7.28.0) and fixes 7 known vulnerabilities without removing or changing any public API that the application code consumes. There is no application logic modified.

No files require special attention — only apps/sim/package.json is touched.

Important Files Changed
